Pocket presence and feel has been one of Carr's weaknesses. He's improving this year despite what's happened the last two weeks. Still, he's the kind of QB who needs more room than some of the other more nimble QBs (McNabb, Favre, Vick et al) to escape a collapsing pocket. He does not have quick feet, nor has he perfected a shuffle inside the pocket (like a Tom Brady) where he can jitterbug his way out of a tight space. If you watch him close, he takes longer strides when he moves around in the pocket and the result is that he can't change direction as quickly and he needs slightly more time to escape pressure. Once/if he breaks free from a collapsing pocket he has good escape speed and is very mobile as we have all seen.
